GPS Mobile Data Collection
By: Man Jim Kong and Chee Keong Lai
Advisor: Dr. B.W. Ellis
The project is based on the functions of the Global Positioning System (GPS). The objective of this project is to monitor positions and temperatures of a mobile unit at various locations in real time. A user ID is used to identify the mobile. We use a GPS Receiver, FM DGPS Receiver, and a temperature sensor to collect the data. A mapping software is written to display the real time positions of the mobile with a valid user ID and the temperatures of the location on a map displayed on the PC.
GPS Remote Tracking System
By: Eric Fosket, Troy Mundt, and Curt Schibonski
Advisor: Dr. J. Rankin
The design is a vehicle tracking system based on a Global Positioning System (GPS) receiver. A vehicle will be equipped with a GPS unit. The positional data as well as other information will be transmitted to a remote location for display on a computer screen. By modifying this design, a fleet of vehicles can be monitored. This project only deals with tracking one vehicle.
High Speed Data Sampling and Processing
By: Tan Kean Hua, Jay Hansen, and Kok Foo Soo
Advisor: Dr. Y. Zheng
The objective is to design and develop a high-speed data sampling and processing board with a PC interface. The design includes the integration of several components. An analog signal can be sampled and converted to 12-bit digital signals at a rate of 40 M BPS. Then the digital signal processor (ADSP-2181) will process the data by performing FFT or other digital filters. This processed data will be transferred to a PC via an ISA bus card and displayed on the screen. This system can be applied to various applications when high-speed data sampling and processing is needed.
Multi-Line Phone System
By: Jim Svare, Duane Stangler, and Steven Cienciwa
Advisor: Dr. A. Narayana
The project involves the design of multiple phone line controller systems. The system will be controlled using a microprocessor, DTMF chips, and standard touch-tone phones. The system will handle two outside lines, and four inside lines. The project's capabilities will be very similar to a PBX (private branch exchange) system, except this design will be able to implement standard touch- tone phones. The project will be assembled on PC cards, with each line having its own card. The CPU will also be on a separate card with the RAM and ROM that will be needed. All cards will be plugged into a back plane that will act as both the analog and digital data bus.
PRML Read Write Error Detector
By: Brad Loren, Theerasut Saraithong, and Robert Corraya
Advisor: Dr. P. George
This project involves the design of an Error Detection System for a PRML Read Channel. The PRML chip puts out digital data that will be operated on by the detector. The theory and operation of the chip will not be discussed in this paper. However, specific conditions relating directly to the design of the detector will be mentioned.
Remote User Circuit Analysis
By: John G. Hedstrom, Brent E. Shouler, and Rob A. Stewart
Advisor: Dr. J.M. Heneghan
The main concept of the Remote User Circuit Analysis Interface with GPIB project is to make it possible for an electrical engineering student to perform circuit analysis via a computer, with the possibility of laboratory use over the World Wide Web. To accomplish this goal, the oscilloscope, function generator, personal computer, and the multiplexer board need to communicate over the GPIB (general purpose interface bus).
RLL 2,7 Read/Write Controller Card
By: Curtis Lyson and Robert Weinberger
Advisor: Dr. S. Lekhakul
On-track International sponsored this project. It reads and writes from an ST506 hard disk drive interface at any location. The project is built upon an 8-bit ISA card. The encoding and decoding of the data from the drive uses an RLL (2,7) format.
Signal Strength Mapping For DGPS Broadcasting
By: Kelly Healy, CarrieAnn Kowalke, and Mark Wendlandt
Advisor: Dr. J. Rankin
The objective of this project is to determine the coverage of Differential GPS signal strength in the state of Minnesota. The DGPS signal is broadcast on the subcarriers of FM radio stations. Therefore, a FM receiver that can tune to the proper frequency and measure the signal strength is required. Also, in order for the measurements to be logged at different locations, a GPS receiver is to be used to combine the signal strength with a geographical location in order to display the signal strength on a map of Minnesota. The map will show the signal strength of the DGPS signal at sampling points at locations in Minnesota by using different colors to represent the various strengths of the signals.
Voice Command Telephone
By: Scott Boeshart and Nhut Vo
Advisor: Dr. S. Lekhakul
The Voice Command Telephone (VCT) is a stand-alone speaker-phone that allows the user to conveniently use voice commands to make and receive telephone calls. After successfully training the VCT after power-up, calls can be made using the voice commands. The VCT involves analog, digital and software design. The project incorporated EE classes including Circuit Analysis, Electronics, Logic Design and Microcontrollers.
